PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 350,395, dated October5, 1886.

Application filed April 15, 1986.

To all whom it may concern:

Be it known that I, JAMES \V. REED, a citi zen of the United States ofAmerica, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inPaddle- WVhcels; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being 11 ad to the accompanying drawings, and to theletters or figures of reference marked thereon, which form a part ofthis specification.

My invention relates to certain new and usefulimprovcmentsinpaddle-wheels; anditconsists 1n the construction and combination of theparts, as will be hereinafter fully set forth,

and specifically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure l isa plan view of a paddle-wheel constructed in accordance with myimprovement. Fig. 2 is a sectional view taken through the line x 00 ofFig. l; and Fig. 3 is a detail perspective view of an angle-plate whichis secured to the radial arms, said angle-plates having also attachedthereto the ends of the paddles.

In the accompanying drawings, A refers to the central shaft of thepaddle-wheel, by means of which the same is secured to the vessehandpower applied thereto for rotating the paddlewheel. This shaft hasrigidly secured thereto by means of clamp-plates a a a seriesof fivesets of radial arms, B B, said radial arms being indicated by theletters I). The arms 6 Z) are secured at their inner ends to the platesor disks a a, which are keyed or otherwise rigidly secured to the shaftA. The terminal portions of these arms which are indicated by the letterB, have attached thereto angleplates G, the edges of which are bent, asshown at c in Fig. 3. These angle or keystone shaped plates are rigidlysecured by means of bolts (1 to the terminal portions of the arms b, andto the bent portion 0 thereof the paddles or boards D are secured bymeans of bolts 6. It will thus be noted that the paddles or boards D aresecured to the arms I) at an angle therewith, and also at an angle withthe main shaft A. The boards or paddles D extend diagonally Serial No.198,904. (No model.)

from one set of arms to the next adjacent set, where they are secured toan angle-plate, G, which is attached to the arms B of said set, thusproviding the wheel circumferentially with a series of diagonal paddles,each paddle attached to said angle-plates,extend therefrom to the spokesof the next set which are not occupied by the paddles of the outer sets.It will therefore be noted that the hubs E have twice the number ofspokes as the hubs E and the central hub, F. The ends of the spokes maybe secured to each other by the circumferential rim, when it is desiredthat they should brace each other.

It will be noted in a paddle-wheel constructed as hereinbefore describedthe paddles will enter the water successively, and when in a verticalposition said paddles will present a horizontal straight line as well asvertical edges. By arranging the paddles as shown in the accompanyingdrawings 1 secure the largest amount possible of bearing-surface, andalso cause the" water to be acted upon so as to create countercurrentswhichbreak to a great extent the wavemot-ion usually produced bypaddlewheels. Whatever wave-motion is produced by my improvedpaddle-wheel is directly and immediately astern and is sent in aconverging direc tion with the course of the vessel. By so doing I amenabled to provide a paddle-wheel of great power, whirh creates but asmall amount of Wave and does not interfere or produce counter-currentsastern which interfere with the steering of the vessel, as the water isnot displaced by the rudder.

I am aware that it has been proposed to construct paddle-wheelsas shownin Patent No. 177,461; but I do not claim such construction, as in saidpatent the paddles between the arms do not occupy opposing angles toeach other, which is a special feature of my improvement,

to twist or turn the paddles so as to accom- :00 and with my improvementit is not necessary lnodate them to the angle of the supporting I sothat the sides of the paddles will converge arms.

I claim- The combination, in a paddle-wheel adapted 5 to be applied atthe stern of a vessel, of a central shaft having secured thereto aseries of hubs, E, E, and F, the center hub, F, and the end hubs, E,having a less number of spokes than the intermediate hubs, E, tapered 1oangle-plates G, with converging flanges sccured t0 the ends of thespokes and paddles D, attached 1:0 the flanges of said angle-plates,

toward the central shaft, while the edges are parallel therewith, theparts being organized r 5 substantially as shown, and for the purposeset forth.

In testimony whereof I allix my signature in presence of two witnesses.
